There are 85 red ,blue and yellow files in a cabnet

There are twice as many yellow files as blue files

There are 3 more blue files than red files

 

How many red files are there?

Let's call the amount of blue files x, so the amount of yellow files is 2x and the amount of red files is 3+x. The sum of these is 4x+3= 85. Solving for x, we get the amount of blue files as 20.5 which means there are x+3= 23.5 red files.

Since you can't have part of a file, I think there is something wrong with your question, the numbers don't add up correctly.

 

Hope it helps!

Ok the questions is solvable now. Doing the same method above, there are x blue files, 2x yellow files, and x-3 red files. So 4x-3= 88 and x= 22. If there are 22 blue files then there are x-3= 19 red files

 

 

Hope it helps!
